Population Density and Spatial-Temporal Niche Use of Ship Rats and Italian Wall Lizards on a Small Adriatic Island. [PDF]
Ecol EvolWe quantified population density and spatial–temporal niche use of ship rats (Rattus rattus) and Italian wall lizards (Podarcis siculus) on a small uninhabited Adriatic islet using spatially explicit capture–recapture, distance sampling, and camera trapping.

Computation of Zagreb Polynomials and Zagreb Indices for Benzenoid Triangular & Hourglass System
Polycyclic Aromatic Compounds, 2022 In this article, we study benzenoid Triangular system and benzenoidHourglass system and we compute Zagreb polynomials for benzenoidTriangular system and benzenoid Hourglass system and from these Zagrebpolynomials we catch up degree based Zagreb indices.

Smarandache-Zagreb Index on Three Graph Operators [PDF]
, 2010 Many researchers have studied several operators on a connected graph in which one make an attempt on subdivision of its edges. In this paper, we show how the Zagreb indices, a particular case of Smarandache-Zagreb index of a graph changes with these ...

Computing Zagreb and Randić Indices of PEG-Cored Dendrimers Used for Drug and Gene Delivery
Journal of Chemistry, 2020 Zagreb and Randić indices are the most commonly used degree-based topological indices in the study of drug design and development. In molecular topology, M-polynomials are also used to calculate the degree-based topological indices of chemical structures.

Bounds on Szeged and PI Indexes in terms of Second Zagreb Index [PDF]
, 2012 In this short note, we studied the vertex version and the edge version of the Szeged index and the PI index and obtained bounds for these indices in terms of the Second Zagreb index.

Computing Topological Indices and Polynomials for Line Graphs
Mathematics, 2018 A topological index is a number related to the atomic index that allows quantitative structure–action/property/toxicity connections. All the more vital topological indices correspond to certain physico-concoction properties like breaking point ...
